The Voices Below

I arrived at the Directorate for Anomalous Research establishment just as the sun rose over Salisbury Plain. The five-storey concrete building stood like a grey scar against the chalk downland, its windowless walls enclosed by a chain-link fence topped with razor wire. Low scrub bent in the exposed wind, and empty military tracks crossed the ranges beyond it. After four years working there, I still could not shake the unease of how ordinary it looked from outside.

It was just another forgettable Ministry of Defence building in the middle of nowhere, designed to disappear into the bleak openness rather than stand out. My staff pass buzzed me through the outer gate, and I parked in my usual space near the eastern entrance. The morning air was cold against my face as I collected my bag and walked towards the door. The establishment housed fewer than forty employees on a typical day, and many had already been reassigned ahead of its announced closure on 31 July 2026.

Gravel crunched beneath my shoes. My thoughts were already racing over what the day might bring. Once inside, I followed the familiar corridors towards the staff kitchen. The fluorescent lights hummed overhead, casting the same sterile glow they always had. Most of the offices I passed were empty, cleared by staff who had moved on to other postings.

My own office was half packed, with cardboard boxes stacked beside my desk in readiness for my final day. I pushed open the staff kitchen door and found Michael Shaw and Thomas Keane already inside. Michael leant against the worktop with a mug in his hand, while Thomas sat at the table studying something on his tablet. They both looked up when I entered.

"Morning, Dave," Michael said, raising his mug. "Ready for another thrilling day of winding the place down?"

I smiled despite my tiredness. "As ready as I'll ever be."

Thomas nodded without speaking and returned his attention to the screen. That was typical of Tom. He was always observing, processing and thinking. I poured myself a cup from the filter coffee machine Michael had started and took a seat at the table.

"Have either of you heard anything new about the closure?" I asked.

Michael shrugged. "Same as before. Two more weeks and this place gets mothballed. All the equipment is being sent to other sites."

"Nobody is saying where or why," Thomas added, looking up from his tablet. "Four years of research, and they're simply ending it."

The rumours had been circulating for weeks. First came the reassignment notices for junior staff, then the equipment inventories, and finally the official memorandum announcing that operations would cease on 31 July. There was no explanation, only the date and instructions for transferring projects elsewhere.

Michael put his mug down harder than necessary. "Do you know what's mad? After all this time, we still don't know what's on the lower levels."

I knew at once what he meant. Despite our security vetting, parts of the establishment remained restricted, particularly the underground levels served by the lifts in the east wing. None of us had ever been cleared to go below ground level.

"The whole place is being shut down," Michael continued, lowering his voice although we were alone. "They'll cart away whatever is down there, and none of us will ever know what we've been working above. Doesn't that bother you?"

Thomas closed the cover of his tablet. "Of course it does."

"Then let's find out," Michael said. His eyes shone with the reckless enthusiasm I had come to expect from him. "The place is closing anyway. What are they going to do, dismiss us twice?"

My stomach tightened. "You cannot be serious."

"Completely serious. Look, I can get a maintenance access card that opens most areas, and Tom has the memory of an elephant. Tell him, Tom."

Thomas glanced towards the door before answering. "I saw Gareth Llewellyn enter the code for the restricted lift. Three times last week, while I was repairing the network panel nearby."

"You memorised it?" I asked, although I already knew the answer.

Thomas's attention to detail was legendary among our colleagues. He nodded. "Six digits. It was not difficult."

I drank some coffee to conceal my unease. Breaking protocol went against everything I believed in, yet the chance to discover what lay beneath us after four years of speculation was undeniably tempting.

"Most of security will be gone after 18:00," Michael said. "They're running a skeleton night crew because of the closure. It's perfect."

"This is insane," I said, but there was no conviction in my voice.

"So you're in?" Michael asked with a grin.

I should have said no. Every rational part of me knew it. But after four years of secrecy, compartmentalisation and unanswered questions, the opportunity to understand what our work had been supporting proved too compelling.

"Yes," I said quietly. "I'm in."

"Excellent." Michael clapped his hands together. "East lift lobby at 18:15. Most of the day shift will have left by then."

We returned to our offices for the morning. When we met again during our lunch break, we planned the details. Thomas brought up the official building plans on his tablet. They showed the ground floor and the four floors above it, but nothing beneath.

Michael outlined what he knew about the security rotations and identified a twenty-minute interval during the shift change when active camera monitoring would be at its weakest.

"I've borrowed a maintenance access card from Priya Nair in security," he explained. "I told her I needed to inspect some server-room equipment after hours."

Thomas volunteered to bring a torch and keep his mobile fully charged. I agreed to stand watch while they operated the lift controls.

When lunch ended and we returned to our respective offices, I could not concentrate on my work. The quarterly review reports I needed to complete remained untouched on my computer while I stared at the screen, imagining what we might find underground. Secret research. Classified technology. Perhaps nothing more than storage for sensitive material.

The hours dragged. I moved papers around my desk, pretended to review documents and answered a few emails, but my thoughts always returned to our planned expedition. Several times I nearly messaged Michael to tell him I had changed my mind. Each time, curiosity overcame caution.

By 17:30, I had abandoned any pretence of working. I shut down my computer and began sorting the last of my personal possessions into boxes. Through my office window, I watched the car park empty as colleagues left for the evening. Cars pulled away one by one, their headlamps cutting through the gathering dusk. The day security staff departed while the reduced night crew took over.

As the wall clock moved towards 18:00, my pulse quickened. I counted the remaining vehicles and matched each one to somebody I knew was still inside. The establishment grew quiet around me, its daytime activity replaced by the hollow silence of a place approaching the end of its existence.

At 17:55, I put on my jacket, trying to look casual in case anyone passed my door. The weight of what we were about to do pressed down on me. I watched the minutes crawl by, knowing that we were close to discovering what DAR had hidden beneath our feet for all those years.

At precisely 18:15, the second hand completed its sweep around my office clock. Half-packed boxes covered the floor beside my desk, and files I had stopped arranging hours earlier lay scattered across its surface. My palms were clammy as I stepped into the corridor and headed for the east lift lobby.

The establishment had changed in the hour since most of the staff had left. Corridors that bustled during working hours now stretched empty before me, my footsteps echoing over the polished floor. A peculiar stillness hung in the air, the kind that settles over places built for people when all the people are gone.

Michael was already waiting at the meeting point, rocking slightly on the balls of his feet. He grinned when he saw me, although the expression did not reach his eyes.

"There he is," he said, far too loudly for the silent corridor. "I thought you might have lost your nerve."

"I said I would be here." I looked around. "Where's Tom?"

Michael checked his watch. "He should be... There he is."

Thomas approached from the opposite direction, walking with measured steps that betrayed none of the anxiety churning inside me. A small rucksack hung from one shoulder. He nodded to us both.

"Who is still here?" he asked quietly.

"Skeleton crew at the security desk," Michael said. "Stephen Hargreaves and Daniel Okafor. They're watching football highlights on one of the monitors instead of the camera feeds."

"Are you sure?" I asked.

Michael shrugged. "I walked past five minutes ago. Trust me, neither of them cares what is happening in this wing."

Thomas opened his rucksack and showed us a compact tactical torch. "I brought this. My mobile is fully charged as well."

"Good." Michael produced a white card from his pocket. "Priya lent me this yesterday. Maintenance access. It should work with the code Tom memorised."

We stood before the lift doors and hesitated. Unlike the other lifts, this one had no floor indicator above it. There was only an access-card reader and a numeric keypad on the wall.

"I'll keep watch," I said, positioning myself where I could see along both corridors. "Be quick."

Michael held the borrowed maintenance card to the reader. A light changed from red to green, and the keypad lit with a soft blue glow.

"Your turn," he whispered.

Thomas stepped forwards. His fingers hovered over the keypad for a moment, then entered six digits with absolute certainty.

I held my breath, half expecting an alarm. Instead, the doors opened with a quiet chime that made all three of us jump.

The car looked ordinary, but its control panel immediately caught my attention. Beneath the button for the ground floor were three additional buttons marked L1, L2 and L3.

"Those levels are not on any plan we've seen," Thomas whispered.

Michael stepped inside. "L3 is the deepest. That's where we're going."

I hesitated with one foot still in the corridor. The sight of those three undocumented buttons made everything real. We were about to breach protocols drilled into us from our first day. If we were caught, we would be dismissed immediately, lose our security vetting and potentially face prosecution.

Yet the mystery beneath us exerted a pull like gravity.

"Dave, come on," Michael urged. "Now or never."

I stepped inside. Thomas pressed L3. The doors closed, and the lift began to descend.

The journey took much longer than I expected. The ordinary lifts travelled between floors in seconds, but this one continued down well beyond any normal depth. None of us spoke as the car hummed. Only a faint vibration beneath our feet indicated our movement.

After nearly a minute, Michael broke the silence. "Do you reckon we'll find alien bodies? A crashed spacecraft the Ministry has been hiding?"

His attempt at humour died in the confined space. His laugh sounded strained.

"Or super-soldiers," he continued, shifting his weight. "Genetic experiments. Two-headed dogs. Standard black-budget material."

Thomas stared at the blank wall where a floor display should have been. "We have been descending for more than a minute. We must be several storeys below ground by now."

"Deeper than the plans ever suggested," I said. "No wonder access is restricted."

The lift slowed and stopped with a slight jolt. For a moment nothing happened. I wondered whether another code was required to let us out, or whether the system had detected that we were unauthorised.

Then the doors opened.

A long corridor extended beyond them, disappearing into shadow past weak ceiling lights spaced too far apart. Its smooth concrete walls lacked the motivational posters and noticeboards found upstairs. Colder air flowed into the lift, stale with the smell of rooms sealed for years.

"Bloody hell," Michael whispered. "We made it."

The moment I stepped into the corridor, I sensed something fundamentally wrong. There was no visible threat, nothing I could identify, only an instinctive certainty that settled over me like a physical weight. The rational part of my mind blamed our breach of protocol and the fact that we were somewhere forbidden.

Something deeper told me otherwise.

"We should not be here," I said before I could stop myself.

"A bit late for that." Michael was already several steps ahead. "Come on. We might have forty minutes before anyone notices."

Thomas switched on his torch and swept its beam over the concrete floor. "The ventilation is different down here. It must use a separate system from the main building."

We moved forwards together. Every footstep echoed in the unnatural quiet. With each one, the sense of wrongness grew, becoming a pressure behind my eyes. Curiosity nevertheless carried me onwards beside my friends and into the darkness.

The corridor seemed like the throat of an enormous creature, swallowing what little light we carried. Its bare grey walls were nothing like the practical but personalised working areas above.

"This is wider than the corridors upstairs," I whispered. My voice travelled much farther than I intended.

Michael swept the light from his mobile across the ceiling. "Government efficiency at its finest. Spend millions on a secret underground level, then neglect the lighting."

Thomas's torch produced a far stronger beam than either of our mobiles.

"We should save its battery until we need it," he said, switching it off again. "Our mobiles will do for now. This can be the backup."

Doors stood along both sides of the corridor at irregular intervals, sometimes close together and sometimes separated by six or nine metres. Unlike the labelled doors upstairs, with their departmental titles and room numbers, these were blank sheets of metal fitted with simple handles.

Thomas tried the nearest one. It did not move.

"Locked."

He tested the next with the same result. Michael crossed the corridor and tried another.

"Same here. I suppose they were never going to leave the interesting rooms open."

We continued, our footsteps creating an unsettling rhythm. The air was dense and stale, as though it had not circulated properly for months. My watch told me we had been below ground for only five minutes, although it felt far longer.

"How large is this place?" I murmured.

"Far larger than the official plans admit," Thomas said as he tried another locked door.

The corridor appeared endless. We passed one identical door after another, and I could not stop imagining what might be behind them. Offices. Storage rooms. Something worse. When my imagination began supplying images that made my skin crawl, I forced them away.

"There's a junction ahead," Michael called.

His light revealed a place where the corridor divided into three passages. We gathered at the intersection and directed our mobiles down separate routes. Each passage was identical to the others, stretching into darkness.

"Wonderful," I said. "Which way?"

Michael looked at his watch. "We have about forty minutes before somebody might wonder where we are. Let's split up and cover more ground. Whatever we find, we meet at the lift in thirty minutes."

A knot formed in my stomach. "Is separating really sensible?"

"We have our mobiles," Thomas said, holding his up. "There is still a signal, surprisingly. If anyone finds something or gets into trouble, send a message."

I wanted to argue, but limited time gave Michael's plan an uncomfortable logic. Staying together meant exploring only one-third of the available passages.

"Fine," I said reluctantly. "Thirty minutes. Back at the lift by 18:45."

Michael was already studying the right-hand passage. "I'll take this one."

"Straight ahead for me," Thomas said, adjusting his glasses as he looked into the central corridor.

"That leaves the left passage for me."

My route curved gently, limiting my view to about fifteen metres.

"See you in thirty minutes," Michael said as he set off. "Do not get lost."

Thomas gave me a small nod before disappearing into the middle passage. I took a breath and began walking down the left-hand corridor alone.

It sloped gradually downwards, giving me the impression that I was descending deeper with every step. Unmarked doors continued along both walls. The few handles I tested were locked.

After perhaps five minutes, I became aware of a sound. At first it was so faint that I assumed I had imagined it. A soft hissing or rushing, like air passing through extractor vents. I stopped and listened.

It lacked the regular mechanical quality of ventilation. It ebbed and flowed.

It sounded like voices.

I walked on, telling myself it was the building settling, water moving through plumbing or pressure changing in boiler pipes. Instead of fading, the sound became clearer. I stopped again and held my breath.

There was no mistaking it now. Many voices were whispering at once, apparently from inside the walls.

"Hello?" I called, regretting it the instant my voice shattered the silence.

The word echoed along the corridor, but the whispering continued without pause. I approached the nearest wall and pressed my ear against it. Cold concrete chilled my skin. The voices became clearer, though not clear enough to understand. Some had the cadence of English. Others spoke languages I could not identify - perhaps German, Russian and several more.

I pulled away and continued. The whispers grew louder with every step, as if their sources were drawing closer or multiplying. My mobile still showed a signal, but I could not bring myself to contact Michael or Thomas. What could I tell them? That the walls were speaking to me?

I tried another handle, partly to reassure myself that physical things still behaved as expected. It turned a fraction and stopped against its lock. The instant I touched it, the whispers surged into frantic agitation, then subsided.

The corridor continued downwards and began curving to the right. My watch said I had been walking for about fifteen minutes. I needed to turn back soon if I was to reach the lift by 18:45.

Then I noticed that the next door was different.

A small rectangular window had been set into it at eye level. I approached with care as the whispers grew more insistent. Holding my face several centimetres back, I raised my mobile and directed its light through the glass.

The beam revealed part of a room far larger than I expected. Rows of shapes stood inside. From that angle they might have been beds or tables. I could not tell.

I leant closer.

The whispers erupted into a near shout.

I recoiled from the door, my heart battering against my ribs. The voices were not coming from the room. They were inside the walls all around me, and now I understood several of the English phrases.

"Get out."

"Leave now."

"Not safe."

Cold dread swept over me. My curiosity vanished beneath a primal need to escape. The whispers were not imagined. They were warnings.

I turned and hurried back the way I had come. Within seconds I was almost running. The voices travelled beside me inside the walls, some strengthening while others faded, as though I were passing different speakers. In the shaking light from my mobile, the corridor seemed to shift and waver.

I rounded the bend that led back towards the junction, desperate to find Michael and Thomas. We had to return to the lift. We had to leave.

Then I stopped.

The whispers pressed around me, repeating their warnings, but another force had taken hold: the thought that we would never have this chance again. DAR would close the establishment in less than three weeks. Whatever lay behind the windowed door might be removed or sealed away for ever.

I stood there fighting myself, every instinct urging me towards safety while curiosity dragged me back. At last, against all reason, curiosity won.

I retraced my steps to the windowed door.

I had roughly fifteen minutes before the meeting time. Fifteen minutes to learn what lay inside.

I tried the handle, expecting the same resistance as before. To my surprise, it turned fully. A security light above the adjacent keypad glowed red, but the locking mechanism had failed or been disengaged. The heavy metal door swung inwards with unexpected ease, releasing a rush of colder air.

I froze on the threshold. My mobile's light cut a feeble path into darkness so complete that it seemed to consume the beam.

The whispers stopped.

The abrupt silence struck like pressure against my eardrums. I took one cautious step, then another. The room extended far beyond what I had seen through the window. My light exposed isolated fragments, too little for me to understand the scale of the place. The floor changed from concrete to smooth tiles that clicked beneath my shoes, and the echo suggested an enormous open chamber.

I moved farther in, sweeping the light from side to side. Indistinct shapes gathered at its edge.

Then the beam found a face.

I stumbled backwards and nearly dropped my mobile.

The face did not move. Once I had steadied my hand, I aimed the light directly at it. A man stared towards me through open, unblinking eyes. He wore modern British Army combat uniform. His posture was rigid and upright, but his boots did not touch the floor. He hung several centimetres above a low platform, supported by something I could not see.

I moved the beam left. Another figure emerged, then another. Row after row extended beyond the reach of the light.

"Hello?" I called.

My voice sounded small in the vast chamber. Nothing answered. Nothing moved.

I forced myself closer to the nearest figure. His skin had an unnatural waxen quality. His eyes were clouded and fixed in an eternal stare. The insignia identified him as a corporal, and the name strip on his uniform read PRICE. EDWIN PRICE.

I waved a hand in front of his face. He did not blink.

As I moved the light over him, the truth became unavoidable. He was not alive. None of them were. They were bodies, perfectly preserved and arranged in immaculate rows. Hundreds of them stood within sight, perhaps thousands beyond it.

I entered the aisle between two rows, moving without conscious intent. The figures wore uniforms from different nations and eras. Some were recognisably British. Others wore German Wehrmacht uniforms from the Second World War. I saw clothing associated with Korea, the Falklands, Iraq and Afghanistan, alongside foreign uniforms from conflicts I could not identify.

They all possessed the same blank stare and unnatural stillness. There was no decay. They might have been placed there days earlier or many decades ago.

"What is this place?" I whispered.

The sound of my own voice startled me.

As though my question had triggered them, the whispers returned. They were louder and more frantic than before, surrounding me from every direction.

"Leave now."

"Get out."

"Danger."

English voices mingled with German, Russian and languages unknown to me, all carrying the same urgency. I turned slowly, illuminating row upon row of preserved military personnel stretching towards the limits of the chamber. Their uniforms had been arranged with inspection-room precision. Some bodies bore bullet wounds, cuts or burns, yet their expressions remained identical.

My shoe struck something set into the floor. I lowered the light and found a metal plate embedded in the tile.

25/06/1950 - 27/07/1953.

Farther on was another.

01/09/1939 - 02/09/1945.

It marked the wider Second World War, rather than the shorter span of British participation. Other sections had plates for the Falklands, Iraq, Afghanistan and conflicts stretching farther back through history.

These were soldiers collected from wars and preserved as specimens.

"Why?" I asked. "Who did this?"

I kept walking, unable to tear myself away despite the chorus begging me to flee. The chamber seemed to expand with every step, revealing still more ranks of bodies.

Then I saw a section of unoccupied platforms.

They stood in ordered rows, waiting for new specimens. The plate set before them read:

2024 -

There was no closing date.

At the far end of the chamber stood a glass door. Beyond it, my light revealed medical tables fitted with restraints, machines I did not recognise and drains set into the floor.

The whispers became a deafening roar.

"Run now, before they come."

My hands shook so violently that the beam danced over the soldiers' faces, lending them the illusion of movement. For a moment they appeared to watch me.

I backed away, turned and ran.

My footsteps thundered through the chamber as the voices rose around me. I burst into the corridor and dragged the metal door shut. It closed with a heavy clang.

The whispers continued inside the walls, driving me onwards. I ran up the gently curving corridor, breathing in quick, shallow gasps. The walls appeared to press in and the ceiling seemed lower than before. Images of clouded eyes and perfectly preserved faces filled my mind.

Whatever DAR had been researching, it was not worth our lives.

The corridor seemed endless as I searched for the junction leading back to my friends and the lift. My lungs burned. The light from my mobile bounced across the concrete, throwing monstrous shadows around me.

At last the three-way junction appeared ahead.

A figure stood motionless in the middle of it.

"Michael!" I called, my voice breaking.

He did not answer.

As I came closer, I saw that Michael's arms hung loosely at his sides. His mobile pointed at the floor, creating a pool of light around his shoes. His face was vacant, his eyes wide and fixed on nothing.

"Mike," I said, moving directly in front of him. "We need to leave. Now."

He did not seem to hear me. His lips moved, forming words too faint to catch. I leant closer.

"The soldiers marching over and over," he murmured. "The children won't stop crying. They're begging for help."

A chill passed through me.

"Michael." I gripped his shoulders and shook him. "Look at me."

His gaze remained unfocused, passing through me.

"Demons in the walls," he said. His body began trembling beneath my hands. "Monsters waiting. They're coming for more."

I shook him harder as panic rose in my chest. "Snap out of it. We need to find Thomas and get out."

At Thomas's name, Michael's eyes cleared slightly. He blinked several times and finally focused on my face.

"Dave?" His voice was small and uncertain.

"Yes, it's me. Where's Tom?"

His face crumpled. Tears gathered in his eyes.

"I don't know. I was walking down the corridor and checking doors. Then I heard voices. Children crying. I followed them to a room with..."

He stopped, shaking violently.

"What did you see?" I asked, although part of me did not want the answer.

"Children. Dozens of them. They weren't moving. They were just standing there as if they had been frozen. Some wore old clothes, like children in black-and-white photographs. Short trousers, braces and pinafore dresses. Others had modern T-shirts and flashing trainers. Every one of them was staring with those empty eyes."

He swallowed.

"And the worst part was the empty spaces. Little platforms waiting for more children."

My stomach turned as I remembered the unoccupied platforms in the military chamber and the open-ended date.

"I found something similar," I told him. "Soldiers and other military personnel, preserved from different periods."

Michael nodded frantically. "Yes. Exactly. A collection. What kind of person would do that? What is this place?"

"I don't know. We need to find Thomas and leave." I looked down the central corridor, the route Tom had taken. "How long have you been standing here?"

Michael looked bewildered. "I don't know. I was in the room, and then... I don't remember coming back."

I checked my watch. "We have about ten minutes before the time we agreed. Have you seen any sign of Tom?"

He shook his head. "Nothing."

"Thomas!" I shouted into the central passage.

My voice returned hollow and distorted. The whispers surged in response, too chaotic now for me to distinguish words.

"Tom!" Michael called beside me.

The voices rose until they almost drowned us out.

"We'll search his corridor," I said.

We moved quickly along the straight passage, our combined mobile lights reaching farther into the darkness. The whispers travelled through the walls beside us.

"Thomas!"

There was no answer beyond that ever-present murmuring. We continued for several minutes, testing doors as we went. Every one was locked. There was no trace of our friend.

Michael seized my arm. "We have to go back. We have to get out."

"What about Tom?"

"Listen to me." His eyes were wild. "The voices are telling me things. Horrible things about what happens to people who stay too long. We need to leave now."

"We cannot abandon him."

"If we stay, we'll become like those people. The voices are warning us. They're trying to help us escape."

I hesitated, divided between loyalty to Thomas and the terror screaming at me to run.

"Five more minutes," I said. "We search for five minutes, then return to the lift. If he does not appear, we'll get help from security."

Michael nodded, although he looked unconvinced. "Five minutes. No more."

We resumed the search at a quicker pace, calling Thomas's name with increasing desperation. The whispers rose and fell with our cries, almost as though they were responding.

"Why would anyone do this?" Michael asked between calls. "Why preserve people that way?"

"I don't know. But it has been happening for decades. Perhaps longer."

Thomas's corridor ended at another junction, where more passages branched into darkness. There was still no sign of him.

"Time is up," Michael said after checking his watch. "We need to go."

I stared into the branching corridors as guilt washed over me.

"Thomas!" I shouted one final time, as loudly as I could.

The whispers swelled to a deafening intensity. Among them, I thought I heard one clear voice.

"Go now."

"Let's go," I said.

We jogged back towards the first junction. When we reached it, we turned for the lift without discussion. The need to escape had overwhelmed every other consideration.

As we approached the lift, Michael caught my arm again.

"What if Tom already found his way back? What if he's waiting upstairs?"

I had not considered it. "Perhaps. God, I hope so."

The metal lift doors looked more beautiful than anything I had ever seen. Michael struck the call button repeatedly, as though force could make the car arrive sooner.

"Come on," he muttered. "Come on."

The whispers grew louder and more insistent. I covered my ears, but the voices seemed to penetrate my hands.

At last the lift chimed and the doors opened. We stumbled inside. Michael immediately pressed the button for the ground floor.

As the doors began closing, movement flickered at the far end of the corridor.

A shadow shifted in the darkness.

"Wait," I said, thrusting out my hand to stop the doors.

"I think I saw something. It might have been Tom."

Michael slapped my hand away and stabbed repeatedly at the button to close the doors.

"No. No way. We're leaving now."

The lift doors slid shut, cutting off my view of the corridor. The lift began to climb, and for a moment I felt almost weightless as it carried us back towards the surface.

"What if that was him?" I demanded, anger mixing with my fear.

"It wasn't," Michael said firmly. His face was pale and drawn. "Trust me, Dave. It wasn't Tom."

We rode in silence after that. The lift hummed around us as it rose from L3. The whispers faded with every level we passed until all I could hear was our ragged breathing and the machinery behind the walls.

What had we done? What had we seen?

Most importantly, what had happened to Thomas?

The lift carried us away from the preserved bodies, the voices in the walls and our missing friend. I could not shake the feeling that we were leaving more than Thomas behind in those dark corridors. We were leaving answers to questions I was no longer certain I wanted to ask.

The doors opened at ground level, and the harsh fluorescent lights struck us like a physical blow. After so long in the darkness below, the ordinary office lighting seemed as bright as stadium floodlights. My eyes watered as I stumbled out, my legs weak and unsteady.

"We made it," I gasped, leaning against the wall to stop myself falling.

I pressed my hands to its cool surface, reassuring myself that it was real and ordinary, unlike the walls below, which had carried whispers.

Michael did not answer. He doubled over and lurched towards a nearby waste bin, retching violently. The sound of him being sick filled the quiet corridor as his body rejected what his mind had endured.

I wanted to help him, but I could not make my legs move. I blinked rapidly, trying to adjust to the light and regain control of myself. The familiar corridor, with its beige walls and non-descript office carpet, looked impossibly mundane after what we had seen underground. It felt as if we had crossed out of a nightmare and back into reality, except the nightmare had been real.

"Thomas," I said suddenly. "We need to ring him."

My hands shook as I pulled out my mobile. It showed a full signal up there, unlike the erratic connection below. I rang Thomas's number and listened.

Voicemail. Straight to voicemail.

"Tom, it's Dave. Ring me the second you get this. We're back on the ground floor by the lift. Mike's with me. We... we need to know you're all right."

I ended the call and tried again immediately. The result was the same.

Michael wiped his mouth with the back of his hand and straightened. His face was ashen.

"Any answer?"

I shook my head. "Voicemail."

"Try again," he urged, his voice raw from vomiting.

I did, with the same result.

"Tom, please ring back. We're worried about you. We're waiting by the lift on the ground floor."

We stood staring at the closed doors as though we could will them to open and reveal our friend. The minutes passed in tense silence, broken only by my repeated calls to Thomas's mobile.

"What if he's still down there with those things?" Michael asked. He slid down the wall until he was sitting on the floor with his knees drawn to his chest.

"They weren't things," I said. "They were people, preserved somehow."

"Like specimens," Michael whispered. "A collection."

I checked my watch. We had already been waiting ten minutes.

"We need to give him more time. Maybe he found another way up."

Michael shook his head. "There is no other way up. We saw the plans."

"The plans didn't show the underground levels either," I reminded him.

We fell silent again. I tried Thomas's mobile every few minutes, but every call went straight to voicemail. The lift remained motionless, its display showing that the car was still at ground level.

After nearly twenty minutes, Michael began rocking back and forth, his arms wrapped around his knees.

"The children wouldn't stop crying," he said, barely loud enough for me to hear. "Behind the glass. They looked perfect, like dolls, but their eyes... their eyes knew what had happened to them."

I did not want to hear it. I did not want to think about what we had seen below.

"Some wore clothes from the forties and fifties," he continued, staring at nothing. "Little boys in short trousers and braces. Girls in pinafore dresses. But others had modern clothes. T-shirts with cartoon characters I recognised. One had flashing trainers. Dave, flashing trainers."

"Mike, stop," I said as my stomach turned.

He did not seem to hear me.

"They were arranged by height. By height, Dave. Who would do that? Who would take children and preserve them like that? And the voices in the walls begged me to help them. They said they'd been waiting so long."

I slid down the wall beside him, needing its support.

"The soldiers I saw were arranged by conflict and period. The Second World War, Korea, the Falklands, Iraq, Afghanistan. There were foreign uniforms too. And there were empty spaces with dates extending into the future."

Michael nodded frantically. "Yes. The children's room had empty plinths as well. As if they're expecting more. Planning for more."

"Who's doing this? What is this place really?" I asked, although I knew he had no answers.

"We should never have gone down there," Michael said, tears streaming down his face. "The voices warned us. They told us to get out."

I checked my watch again. Twenty-five minutes had passed since our return to ground level.

I rose on shaking legs and pressed the call button. The doors opened on an empty lift.

"I'm going back down," I announced, surprising myself.

Michael stared up at me in horror. "No. Are you mad? We barely got out."

"Thomas is still down there. We can't just leave him."

"He could be anywhere in those tunnels by now," Michael argued. "Or he could be..."

He could not finish. I knew he was right. The maze of corridors had seemed endless, and we had no way of knowing how far Thomas had gone or what he had found.

But abandoning him felt wrong. Cowardly.

I stepped back from the lift and let the doors close.

"Maybe you're right."

Michael pulled himself upright, still unsteady. "We need help. Real help."

"Security," I agreed. "We'll tell them Thomas is missing."

"What about everything else we saw?"

I had not thought that far ahead. "I don't know. But Thomas's safety comes first."

We waited another twenty minutes, continuing to ring him without success. Every minute that passed made it less likely that he would suddenly emerge.

"It's been forty-five minutes," I said at last. "We need to report this."

Michael nodded, his eyes red and swollen. "What are we going to tell them?"

"The truth. That we went exploring where we shouldn't have, became separated, and now Thomas is missing."

"They'll sack us," Michael said. "Maybe worse."

"I don't care. If there's even a small chance they can help Tom, we have to do it."

We walked slowly along the corridor towards the security station. My mind raced through what I would say. I needed to emphasise that Thomas might be in danger and that finding him mattered more than punishing us for breaking the rules. I would admit that we had used Priya Nair's borrowed maintenance access card and the code Thomas had memorised while watching Gareth Llewellyn. I would take full responsibility if necessary.

I rehearsed the words as we approached the security desk at the main entrance. Two guards sat behind the monitors. One was watching football highlights on a small screen. They looked up, and their expressions shifted from boredom to alertness when they saw our dishevelled state.

"We need help," I said, my heart pounding. "Our friend is missing."

The guards exchanged a look I could not interpret. I realised that this moment would determine whether we received the help we desperately needed or faced consequences I could not begin to imagine.

The older guard, whose badge read STEPHEN HARGREAVES, put down his mug of filter coffee and turned fully towards us.

"Missing?" he asked in a flat, professional voice. "Who is missing?"

"Thomas Keane," I said. "He's one of our colleagues. We were... we were down in the restricted area, and we became separated. We can't find him."

I expected shock or anger at our unauthorised access, but Hargreaves's expression did not change. He gave a slight nod, as though I had told him the filter coffee machine was broken.

"When did you last see him?" he asked, taking a notepad from his desk drawer.

"About an hour ago. At the junction where the corridor divided into three. He went straight ahead."

Michael stepped forwards, still pale and sweating.

"You don't understand. There's something wrong down there. We saw things - horrible things. People preserved like... like specimens. Children and soldiers, standing there, not moving or breathing, with these empty eyes."

Hargreaves silenced him with a raised hand.

"Sir, I need to concentrate on locating your missing colleague. Those other matters are above your security vetting."

Above our security vetting. Not, "I don't know what you're talking about," or, "You must be mistaken."

He knew exactly what we had seen.

"You know about those rooms?" I asked. "About the preserved people?"

Hargreaves remained perfectly composed. "I need your staff passes, please."

Michael and I looked at each other, then slowly took out our passes and handed them over. Hargreaves examined them, copied our details into his notepad and passed them to the younger guard.

"Daniel, call it in," he said. "Code Wayward. Two returnees, one outstanding."

Code Wayward. Returnees. Outstanding.

They had terminology for this situation. It had happened before.

Daniel Okafor lifted a telephone and dialled a number from memory.

"Security desk, ground level. We have a Code Wayward situation. Two returnees present, one outstanding. Staff numbers..."

He read our numbers from the passes.

"Yes, sir. Understood."

My mouth went dry.

"What's happening? Are you sending people to look for Thomas?"

Hargreaves leant back in his chair and studied us with detached interest.

"Appropriate measures will be taken. How are you both feeling? Any nausea? Headaches? Auditory hallucinations?"

"The voices," Michael whispered. "You know about the voices in the walls."

Hargreaves neither confirmed nor denied it. He merely made another note.

"When did the voices begin? Could you understand what they were saying?"

"They were warnings," I said. "They told us to leave, to get out while we still could."

Hargreaves nodded as if I had confirmed something he already knew.

"And the missing employee, Thomas Keane - did he report hearing these voices as well?"

"I don't know," I admitted. "We became separated before..."

I trailed off, realising how little I actually knew about what had happened to Thomas.

"Please take a seat." Hargreaves indicated a row of chairs against the wall. "Someone will be here shortly to assist you."

"Assist us?" Michael's voice rose. "We don't need assistance. Thomas does. He's still down there with those... those things."

Hargreaves's expression did not alter.

"Sir, please lower your voice and take a seat."

We sat, although every instinct told me to continue arguing and demand action. The calm, procedural way they handled our panic was almost as disturbing as what we had seen underground.

Michael leant towards me.

"They know, Dave," he whispered. "They know about all of it."

I nodded. Hargreaves continued making notes while Daniel Okafor watched the security monitors, occasionally glancing towards us. Neither man appeared concerned or surprised by our account.

"Do you think Tom is all right?" Michael asked quietly.

Before I could answer, the main entrance doors opened. Two people in dark suits entered and walked towards us with purpose. They did not resemble the usual security staff or researchers. Their postures were too rigid, their expressions too controlled.

Hargreaves rose as they approached.

"The returnees are here."

The taller of the pair, a man, nodded. "We'll take it from here."

I found myself standing, although I did not remember deciding to move.

"What about Thomas? Are you sending people to find him?"

The man turned to me, his face blank.

"Mr Mercer, correct?"

I nodded, uneasy that he knew my name without asking.

"I am Officer Alistair Vane. This is my colleague, Officer Ruth Calder. We would like you to come with us, please."

"Where?" Michael demanded, standing as well.

"Only to the conference room," Vane said smoothly. "We need to debrief you about this evening's events."

"What about Thomas?" I repeated.

"A team has already been dispatched," Calder said. Her voice had a practised quality, as though she had spoken those exact words many times before. "Your co-operation will help us locate your colleague more efficiently."

I did not believe her, but we had little choice. We followed them along the corridor towards the main conference room, the same room where we had attended quarterly review meetings throughout our four years at the establishment.

The lights were already on. Two folders lay on the table, one bearing my name and one Michael's.

Vane and Calder gestured for us to sit, then took places opposite us.

"At what time did you enter the restricted area?" Vane asked without preamble.

"At about 18:15," I said. "But shouldn't you be concentrating on finding Thomas instead of questioning us?"

Vane ignored the question.

"You separated at the junction approximately ten minutes later?"

"Yes," Michael said. "I took the right-hand corridor, Tom went straight ahead and Dave took the left."

"What did you see in your respective corridors?" Calder asked, opening a laptop.

Michael glanced at me, then back at the officers.

"I found a room full of children. They were preserved somehow, standing upright and completely still. They came from different periods. Some looked as if they were from the forties or fifties. Others were modern. There were empty plinths too, as if they were waiting for more children."

I expected disbelief or at least surprise, but Calder simply typed his statement.

"And you, Mr Mercer?" Vane asked.

I swallowed.

"A similar room, but filled with soldiers. Military personnel from different wars and different countries, also preserved. There were empty plinths labelled with future dates."

Calder kept typing. Neither officer reacted.

"The voices," Michael blurted. "What are they? Why are they in the walls?"

Vane and Calder exchanged a brief glance.

"That information is classified," Vane said. "Now, did either of you enter any other rooms or interact with any of the preserved specimens?"

"They aren't specimens," I snapped. "They're people. Dead people preserved like museum exhibits. Who is doing this? What is this establishment really for?"

Vane looked at me with something like pity.

"Mr Mercer, the Directorate for Anomalous Research deals with matters beyond standard classification. The less you know, the better it may be for your psychological well-being."

"Our psychological well-being?" Michael gave a high, thin laugh, nothing like his normal easy humour. "I saw preserved children, with empty spaces waiting for more, and you're concerned about our psychological well-being?"

Calder closed her laptop.

"We understand that this has been traumatic. That is precisely why protocols exist for these situations."

Protocols. Procedures for precisely this kind of breach.

It had happened before.

"How many others?" I asked suddenly. "How many other employees have found their way downstairs?"

Neither officer answered, but their silence told me enough.

"What happened to them?"

Vane sighed. He reached into his jacket, took out two envelopes and slid them across the table.

"Your employment with the Directorate for Anomalous Research is terminated with immediate effect. These letters contain the details of your termination payments, which are generous in the circumstances."

I stared at the envelopes. The folders and dismissal documents had been prepared with impossible speed. Code Wayward was clearly a rehearsed protocol. They had not predicted that the three of us would enter L3 that evening, but they had been ready for whoever eventually did.

"What about Thomas?" Michael asked, his voice breaking.

"Mr Keane's situation will be handled according to established protocols," Calder replied.

"What does that mean?" I demanded.

"It means that you should focus on your own futures," Vane said. "Two black Range Rovers are waiting outside to take you home. Your personal belongings have been packed and will be delivered to your respective flats tomorrow."

"That's it?"

Michael shot to his feet, his chair scraping loudly across the floor.

"Thomas is missing. We've seen things no one should ever see, and you're simply sending us home with dismissal letters."

"Mr Shaw," Vane said, his voice cooling, "I should remind you that your employment contract included extremely strict confidentiality provisions. Discussing anything you have seen this evening with anyone, including each other after you leave this establishment, may lead to prosecution under the Official Secrets Acts and a potentially lengthy prison sentence."

"You're threatening us," I said.

"I am reminding you of legal obligations to which you have already agreed," Vane corrected me. "Now, shall we proceed to the exit?"

We were given no choice. Vane and Calder escorted us along the corridors towards the main entrance. The building felt different now. It was no longer merely a workplace with a few restricted areas. It had become something alien and threatening.

How had I spent four years there without sensing what lay beneath us?

At the security desk, Stephen Hargreaves handed us temporary visitor badges in place of our staff passes.

"Give these to the drivers when you reach your destinations."

"Stephen," I said, reading his full name from his badge. "You know what's down there. How can you work here, knowing that?"

Hargreaves looked at me with eyes that reminded me too much of the preserved bodies.

"Good evening, sir. Please proceed to the vehicles."

Outside, two black Range Rovers idled in the car park. A suited driver stood beside each one.

"Mr Shaw, the vehicle on the left," Vane directed. "Mr Mercer, the one on the right."

"You're separating us?" Michael asked, suddenly panicked.

"Standard procedure," Calder said smoothly. "The drivers will take you directly to your homes."

Michael seized my arm.

"Dave, what about Tom? We can't just leave him."

I did not know what to say. What could we do against an organisation that had plainly dealt with this situation many times before?

"Mr Shaw, please proceed to your vehicle," Vane said, his tone hardening.

Michael's grip tightened.

"Dave, the voices knew. They tried to warn us."

"I know," I said quietly. "Mike, we'll talk tomorrow, all right? We'll work something out."

He nodded reluctantly and released me. We walked towards our separate vehicles.

When I reached mine, I looked back at the five-storey concrete establishment, a bland structure concealing horrors I could scarcely comprehend. The driver opened the rear door.

"Sir."

I hesitated, thinking of Thomas somewhere in those underground corridors. Would he end up like the preserved figures? Was that what happened to people who remained below too long?

As I climbed into the back seat, I caught a final glimpse of Michael getting into the other Range Rover. His face was turned towards the building, his expression lost and broken.

The door closed beside me with a heavy thud. The driver got in and pulled away without a word. In the side mirror, I watched the DAR establishment diminish against the blackness of Salisbury Plain until the building disappeared, taking Thomas and its secrets with it.

I did not sleep.

The Range Rover dropped me outside my block of flats shortly after midnight on Monday, 13 July 2026. The driver said nothing beyond, "We have arrived, sir," before I stepped out into the empty car park.

I spent the remainder of the night sitting at my kitchen table and jumping at every creak in the walls. My mind replayed images of soldiers preserved like museum exhibits, and of whispers that seemed to have followed me home.

Morning light streamed through the blinds, falling across the white envelope on the table. I had opened it hours earlier and read the dismissal letter again and again.

Its language was cold and precise. Employment terminated with immediate effect. Security breach. Breach of confidentiality. Nine months' salary as a termination payment.

There was no mention of Thomas. No acknowledgement of what we had seen. The letter did not even name DAR. It was merely bloodless departmental language concealing something monstrous.

My mobile buzzed for the third time since 06:00. Michael again.

I answered.

"Dave, are you there?"

His voice sounded thin, stretched almost to breaking point.

"Yes, I'm here," I said, rubbing my eyes.

"Did you sleep at all?"

"How could I?"

Michael gave a hollow laugh, nothing like his usual humour.

"Every time I close my eyes, I see those children standing there, staring at nothing. And the voices..."

"Can you still hear them?"

"No," I lied.

The truth was that I kept imagining whispers in the bathroom plumbing, the extractor vents and the walls themselves. Admitting that would only make Michael worse.

"I can," he said. "They're quieter up here, but they're still talking. Saying things. Asking me to come back."

I gripped the mobile more tightly.

"That's the stress, Mike. It isn't real."

"It was real down there," he countered. "You heard them too."

I could not argue with that.

"Have you heard anything from Thomas? Any calls or messages?"

"Nothing." Michael's voice cracked. "Dave, what if he's become one of them? What if they took him and preserved him like the others?"

The image struck me like a blow: Thomas standing motionless, his eyes clouded, another specimen in that appalling collection.

I forced it away.

"I'm going to try his family," I said. "His sister, Helen Keane, lives in Newcastle upon Tyne, I think. He mentioned her once."

"All right. Ring me back. I need to know he's safe."

After the call, I pulled my laptop towards me and logged into the employee portal we had used at work. To my surprise, my main credentials still worked, but a search for Thomas Keane returned nothing. His profile had been removed as though he had never worked there.

I tried the human resources section, where emergency contact details would have been kept. My access to it had already been revoked.

Every trace of Thomas had been systematically erased overnight.

My mobile buzzed again.

"Any luck?" Michael asked immediately.

"No. They've already scrubbed him from the system. It's as if he never existed."

Michael was silent for a moment.

"I'm coming over," he said at last. "I can't stay here alone. The walls keep talking."

"All right," I said, increasingly worried about him. "Do you need me to collect you?"

"No. I'll drive. I'll be there soon."

After he rang off, I tried to put my flat in order. Empty coffee mugs from my sleepless night littered the worktops. The blinds remained drawn, making the place feel shuttered and hidden. I opened them and let the sunlight flood the sitting room.

Salisbury spread below my second-floor flat. Ordinary people went about ordinary lives, unaware of chambers beneath the chalk downland where preserved bodies stood and walls whispered warnings.

By midday there was a knock at my door. Michael stood in the corridor with a bottle of whisky in one hand and a rucksack slung over his shoulder. He looked dreadful. His hair was unwashed, his eyes bloodshot, and dark stubble covered his normally clean-shaven face. He had at least changed his clothes, although his shirt was buttoned incorrectly.

"You look like hell," I said, stepping aside.

"Feel worse," he muttered.

He went straight to the kitchen and set the whisky on the worktop.

"Have you got any glasses?"

I checked the time.

"It's barely midday, Mike."

He stared at me in silent challenge. I sighed and took two tumblers from the cupboard. He was going to drink with or without me, and I wanted to keep him talking.

Michael poured a generous measure into each glass, pushed one towards me and swallowed deeply from his own. He winced as it went down.

"So, what's your theory?" he asked, leaning against the worktop. "Government experiments? Alien technology? Some preservation technique nobody outside DAR has ever heard of?"

I took a small sip and felt the whisky burn my throat.

"I don't know. Some of those bodies looked decades old, but there was no decay."

"The children's room had children from at least the forties," Michael said, staring into his glass. "I recognised the clothing. But others wore modern clothes. They've been collecting them for generations."

"The soldiers were organised by conflict," I said. "The Second World War, Korea, the Falklands, Iraq and Afghanistan. There were more recent sections and uniforms from other countries too. Not just British personnel."

Michael drank again.

"Who would do it? And why? What's the point of preserving dead people like that?"

"Are we certain they were dead?" I asked.

It was the question that had haunted me all night.

Michael looked sharply at me. "What do you mean?"

"They weren't breathing or moving, but something felt wrong. It was different from looking at a corpse."

"They were standing upright," Michael said slowly. "No visible supports. No rigor mortis. Perfect preservation."

We fell silent, both considering implications too horrible to voice.

"And the voices," I said at last. "Where did they come from? Why could we hear them?"

Michael finished his drink and poured another.

"They warned us. Told us to leave, as if they were trying to help."

"But who were they?"

"Former employees? Earlier specimens?"

Michael shuddered.

"Last night I had dreams. Nightmares. I was standing in the room with the children, but I couldn't move. I couldn't speak. I could only watch while people in white coats examined me and made notes. But I was aware, Dave. Completely aware."

He looked at me, his eyes wide with fear.

"What if they're all still aware in there? What if they can see and think, but they can't move or speak? What if that's what happened to Tom?"

I felt cold despite the warmth of the flat.

"We don't know that. He might have found another way out."

"You don't believe that," Michael said flatly. "You saw how those officers reacted. This has happened before. They have protocols."

I walked to the sitting-room window and looked down at the quiet street.

"We should call the police. Report Thomas missing."

Michael laughed bitterly.

"And tell them what? That our friend disappeared inside an undocumented underground level at a secret Ministry of Defence research establishment full of preserved bodies?"

"We don't have to mention the bodies. We can say he went missing at work."

"Did you miss the part where they threatened us with prosecution under the Official Secrets Acts?"

Michael emptied his second glass.

"They've already erased him from the employee directory. They've covered their tracks."

I knew he was right.

When I turned back, he was taking a laptop from his rucksack.

"I've spent all morning researching the Directorate for Anomalous Research," he said, opening it on my coffee table. "There's almost nothing."

He showed me the results: a handful of vague government contract notices and spending allocations buried in obscure departmental reports. There was nothing about an establishment on Salisbury Plain or any specific research programme.

"It's as if DAR barely exists on paper," I said, scrolling through the meagre findings.

"Or they've scrubbed their public-facing presence," Michael replied. "Look at this."

He opened a Department for Energy Security and Net Zero spending report from two years earlier. It referred obliquely to substantial funding for specialised containment research. Following the trail through linked departmental accounts suggested that the money had ultimately been routed through the Ministry of Defence, but the next year's report contained no equivalent entry and no mention of DAR.

"They're hiding in plain sight," Michael said. "Black-budget operations disguised as dull research initiatives. Defence, Cabinet Office, or energy? Move the money between them and nobody outside the system knows where it ends up."

We spent several hours searching every source available to us: archived GOV.UK pages, Ministry of Defence publications, departmental accounts, contract notices, Companies House records and scientific journals. DAR appeared occasionally in bureaucratic fragments, but nothing contained substantial information about its work.

As evening approached, Michael drank more heavily and his theories grew increasingly elaborate. The preserved bodies were failed experiments. They had been created with alien technology. They housed consciousnesses trapped by government weapons. Every explanation sounded more desperate than the last.

I ordered a curry takeaway and tried to make him eat something besides whisky. He picked at it while continuing his frantic search for answers.

"Dave," he said suddenly, his voice tight, "what if they come for us next?"

"What do you mean?"

"We saw things we weren't supposed to see. We know too much." His hands were trembling. "What if they decide we're a liability?"

"They let us go," I reminded him. "They gave us termination payments."

"To keep us quiet. But what if they're watching us? What if they're listening now?"

I glanced involuntarily around the flat.

"If they wanted us gone, I think we'd already be gone."

Michael leant towards me and lowered his voice.

"Or preserved. Standing in those rooms with all the others. Another specimen in their collection."

I put down my fork, my appetite gone.

"Mike, you need sleep. You're spiralling."

"I told you, I can't sleep."

He stood and began pacing the small sitting room.

"Whenever I close my eyes, I hear them. The voices in the walls. They're calling me back, Dave. They want me to come back."

I went to him and placed my hands on his shoulders.

"Listen to me. You're exhausted and traumatised. We both are. But those voices aren't here. They were only inside the establishment."

Michael looked at me, his eyes unfocused.

"You don't hear them now? Whispering? Warning you?"

"No," I lied again. "And neither do you. It's your memory playing tricks on you."

He pulled away and ran both hands through his unwashed hair.

"What about Thomas? Do we simply abandon him?"

"We don't have a choice," I said, the words bitter in my mouth. "We can't return to the establishment. We can't tell anyone what we saw. We can't report him missing without exposing ourselves."

"So we do nothing?" Michael's voice rose. "We let them get away with it?"

"What else can we do?" I asked as frustration and helplessness overwhelmed me. "You saw how prepared they were. Code Wayward, the dismissal folders, the clean removal from the site. We aren't the first people to discover what's down there, Mike. They've perfected the way they deal with people like us."

Michael collapsed on to the sofa, all the fight draining from him.

"So that's it. We simply live with this."

I sat beside him.

"For now. Until we work out what else we can do."

But as darkness settled beyond the windows, I understood the terrible truth. We were entirely alone. Thomas was beyond our reach. Nobody would believe our story.

Somewhere beneath the windswept emptiness of Salisbury Plain, DAR continued its work, collecting and preserving its specimens while voices in the walls whispered warnings to anyone who ventured too deep.

Michael finally passed out on my sofa at about 03:00 on Tuesday, 14 July, overcome by whisky and exhaustion. I covered him with a blanket and went to bed, but sleep would not come.

I heard noises throughout the flat: plumbing contracting, the extractor vent rattling, water moving through boiler pipes and the faint knocking of radiators. My mind transformed every sound into the whispers from below.

When Michael woke later that morning, he looked worse than before. A few hours of unconsciousness had not refreshed him. Dark circles hung beneath his bloodshot eyes, and he moved like a man twice his age.

"I need to go home," he mumbled as he packed away his laptop. "I need to do more research."

"You should stay. We can investigate together."

He shook his head.

"I can't think properly here. I need my own space."

I walked him to the door, worried that he was in no condition to drive.

"Ring me when you get home, all right? Just so I know you made it."

"Yes. All right."

He paused in the doorway.

"Dave, do you really not hear them any more? The voices?"

I hesitated. I had heard what sounded like distant murmuring all night, but admitting it would feed his obsession.

"No," I lied. "Only the usual noises in the flat."

He studied my face for a moment.

"Lucky you."

That was Tuesday.

By Wednesday afternoon, 15 July, I was worried because Michael had stopped returning my calls. I drove to his block of flats and knocked on his door for almost five minutes before he answered.

The smell reached me first: stale alcohol, an unwashed body and something else, sour and wrong.

Michael stood in the doorway wearing the same clothes as the day before, now crumpled and stained.

"What do you want?" he asked, his words slightly slurred.

"I'm checking on you," I said, pushing past him into the flat. "You weren't answering your mobile."

His sitting room had been transformed. Printouts covered every surface - the coffee table, the sofa and even the walls, where he had fixed them with adhesive tape. There were news articles, research papers, government documents and posts from conspiracy blogs. Sections had been highlighted or circled in red, with Michael's cramped notes filling the margins.

"I've been busy," he said, closing the door. "I found things."

I picked up the nearest document. It was a declassified Cold War behavioural-research paper from the 1970s. Beside it lay a printout about alleged consciousness studies conducted during the 1980s.

"Mike, have you slept at all?"

He ignored the question and snatched a stack of papers from the sofa.

"Look at this. Similar establishments all over Britain, hidden underground. Black-budget projects."

I scanned the pages. Most came from conspiracy sites with questionable sources. A few appeared to be genuine government papers relating to research establishments, but nothing directly connected them to what we had seen.

"You need to eat," I said, noticing an empty whisky bottle on the kitchen worktop. "Let me make you a sandwich or order something."

"I'm not hungry," he muttered, shuffling through more pages. "The voices get louder when I eat. They don't like it."

A chill ran through me.

"Mike, the voices aren't real. They can't be here."

He looked sharply at me.

"Then how do they know things? How do they tell me about the other sites? About the collection programme?"

"What collection programme?"

He pulled a crumpled sheet from his pocket.

"Project Afterimage. It started in 1945. Preservation of human specimens for long-term observation."

The page was a photocopy of what appeared to be an official document, but its heading and almost every identifying detail had been obscured by thick black bars.

"Where did you get this?"

"A dark-web forum. People who worked at places like ours. They know."

I put the paper down.

"You need help, Mike. Professional help. A psychiatrist or another mental health professional."

He laughed bitterly.

"What would I tell them? That I found preserved bodies under a secret government establishment? That the walls talk to me? They'd send me for an urgent mental health assessment at A&E."

"You don't have to tell them everything. Say that you can't sleep and that you're hearing things. We can call an NHS urgent mental health helpline."

"They wouldn't believe me," he interrupted. "Nobody would except you. You were there."

I spent hours trying to persuade him to eat, shower and rest. He eventually ate half a sandwich I made for him, but he refused to stop researching. I left that evening only after making him promise to ring me if his condition worsened.

Thursday, 16 July, followed the same pattern. When I visited, there were more printouts, more frantic theories and more evidence of his decline. He had begun writing directly on the walls, covering them with dates, names and locations linked into a web that made sense only to him.

I brought groceries and cooked a simple meal. He picked at it while explaining his latest theory: DAR was capturing the souls or consciousnesses of the dead and preserving them inside artificial bodies.

"That's why they can talk through the walls," he said, his eyes feverishly bright. "They aren't fully contained. Parts of them leak out."

Friday, 17 July, was worse.

Michael stopped answering his door, so I used the spare key he had given me years before. I found him sitting unwashed and unshaven on the floor, surrounded by papers and muttering to himself.

"They want me to come back," he said when he noticed me.

They keep saying they need help.

I helped Michael into the shower, cleared away the empty whisky bottles and opened the windows to disperse the stale air. While he washed, I gathered the most disturbing notes and printouts from his walls and hid them in a kitchen cupboard. He needed less fuel for his delusions, not more.

"You should stay with me again," I suggested when he emerged in clean clothes, looking marginally more human.

"Can't," he said. "Need to keep working. Nearly figured it out."

"Figured what out?"

"How to help them. The voices. They're trapped. Been trapped for years."

I tried another approach. "Mike, what about Tom? Shouldn't we be concentrating on what happened to him?"

Michael's face crumpled.

"Tom's one of them now," he said. "I hear him sometimes at night. His voice is different, but I know it's him."

That night, Thursday, 16 July 2026, I rang an NHS urgent mental health helpline and explained the situation as vaguely as I could. The adviser recommended taking Michael to A&E for an urgent mental health assessment, but warned that he might be kept under observation if he said he was hearing voices. Given what we knew about the DAR and its determination to keep us silent, I was terrified of what might happen if Michael began talking about preserved bodies and secret underground levels while under psychiatric care.

On Friday morning, 17 July 2026, I woke to a message from him.

Sorry for everything. Never should have dragged you down there.

Something about the wording set alarm bells ringing. I called at once, but it went straight to voicemail.

I tried three more times while pulling on clothes and grabbing my car keys. The drive to Michael's block of flats took twenty minutes in the morning traffic. Every minute stretched like an hour. I kept ringing his mobile and kept reaching voicemail.

I told myself he was asleep. His battery had died. There had to be some explanation other than the one becoming more certain with every unanswered call.

I abandoned my car crookedly in the car park and ran into the building, taking the stairs two at a time to his second-floor flat.

His door was locked. I hammered on it and shouted his name, drawing a wary glance from a neighbour who quickly withdrew into their own flat. My hands shook as I fumbled with the spare key. The door opened upon a home in even worse disorder than before.

Papers covered the floor. Empty bottles and takeaway cartons crowded every surface. There was no sign of Michael in the sitting room or kitchen.

"Mike?" I called, moving towards the bedroom. "Are you here? Answer me, mate."

The bedroom door stood partly open. I pushed it wider and saw the unmade bed, clothes strewn across the carpet and still more papers fixed to the walls. The wardrobe door was closed.

I knew before I opened it. Some part of me already understood exactly what I would find.

Michael had used his belt, a sturdy leather one I recognised, fastening it to the rail inside the wardrobe. His eyes were open but unseeing. His expression bore no resemblance to the vacant faces of the preserved bodies. It was worse because it was so unmistakably final.

My legs gave way. I collapsed to the floor and dragged my mobile from my pocket with numb fingers. I called 999 and gave the operator the address in a voice that did not sound like mine.

On the chest of drawers, a single sheet of paper had been propped against a lamp. Seven words were written in Michael's increasingly erratic hand.

Can't stop the voices. They want me back.

The next few hours passed in a blur. The ambulance crew confirmed what I already knew. Police officers asked questions, and I answered mechanically.

Had he appeared depressed?

Yes.

Had he threatened to take his own life?

Not explicitly.

Did he have a history of mental illness?

Not that I knew.

They showed little interest in the note. Depression, they concluded, probably worsened by alcohol. They asked whether he had any relatives who should be told, and I gave them what little information I had about his estranged sister, Rachel Shaw, in Exeter.

Nobody asked about our jobs or why we had both been summarily dismissed. Nobody questioned the strange research papers covering the flat. To them, it was another private tragedy, another death to process. A detective took my statement in Michael's sitting room while the ambulance staff and police completed their work in the bedroom.

He asked whether I wanted information about bereavement counselling. I nodded without really hearing him.

"There is nothing you could have done," he said, handing me a card listing support services. "When somebody reaches this point, it can be very difficult to stop them."

But he was wrong. There were things I could have done. I could have prevented Michael from going down to L3. I could have reported Thomas's disappearance to outside authorities immediately. I could have taken Michael's deterioration more seriously.

Eventually they left me alone in the chaos of the flat. Michael was gone. The police were gone. All that remained was the evidence of my friend's final frantic days, scattered across the rooms.

I began gathering the papers and reading his notes more carefully. Most were disjointed, paranoid fragments, but some contained information too precise and detailed to dismiss easily. There were coordinates for other alleged facilities, names of officials supposedly connected to Project Afterimage and dates stretching back for decades. In one notebook, Michael had written:

They preserve the body but trap the consciousness.

Decades of awareness without the ability to move or speak. Only the walls let them communicate.

Had the voices truly told him that, or had his mind invented an explanation for the horrors we had witnessed? I would never know. Michael was dead. Thomas was missing, almost certainly trapped and possibly dead, but there was no proof of what had become of him. I was still alive, still hearing occasional whispers in the radiators, plumbing and boiler pipes. They might have been ordinary household sounds. They might have been something far worse.

I packed Michael's research into three heavy-duty refuse sacks. I could not leave it for his landlord or his family to discover. I could not risk drawing somebody else into the nightmare. I did not know whether I would destroy everything or continue the work Michael had begun.

Standing in my dead friend's flat, I could not make that decision. All I knew was that Michael was dead and Thomas was almost certainly trapped because we had gone where we should never have gone. For reasons I could not understand, I had survived. The weight of it pressed upon my chest until I could scarcely breathe.

I carried the sacks to my car, glancing over my shoulder and half expecting to see black Range Rovers watching from the road. The sky was a clear summer blue. The day continued as though nothing had happened, as though Michael Shaw had not ended his life because of what we had found beneath our workplace.

I sat behind the wheel with both hands clamped around it, unable to start the engine.

In the five days since our descent on Sunday, 12 July 2026, I had lost one friend and seen the other erased. Five days since we had taken the lift down to L3. Five days since we had learnt that some secrets should remain underground, behind locked doors whose walls whispered warnings to anyone foolish enough to enter.

Michael's funeral took place on Monday, 27 July 2026. The service was small. There was me, Rachel, who had travelled from Exeter, and a handful of former colleagues who had not been told the circumstances of his death. Nobody representing the Directorate for Anomalous Research attended. Nobody mentioned Thomas.

Two days later, on Wednesday, 29 July 2026, I drove back across Salisbury Plain. I told no one where I was going.

My flat still seemed charged with Michael's desperate energy, its air tainted by the memory of the papers I had taken from his walls. They now filled a locked filing cabinet in my spare room. They were evidence of his decline that I could neither destroy nor bear to examine.

The familiar journey across the chalk downland felt shorter than it had during my four years of employment. Wind swept over the open ranges, flattening the long grass beside the military tracks and worrying at the low scrub. Morning light cast stretched shadows across the pale earth.

About a mile before the main gate, after I turned on to the MoD access road, I saw the demolition plant.

Excavators and mobile cranes surrounded what remained of the five-storey concrete research establishment. The permanent outer fence had been supplemented with temporary chain-link barriers bearing signs that read DANGER - DEMOLITION IN PROGRESS.

I pulled on to the grass verge and watched through the windscreen. Workers in safety helmets moved across the site like ants, carrying out a carefully choreographed dismantling. Half the main building had already been reduced to rubble.

The surviving portion stood open to the air, its floors exposed like the shelves of a bookcase. All the equipment, furniture and internal walls had been stripped away.

I got out and walked towards the barrier, remaining far enough back not to attract attention. The exposed wind tugged at my coat as I studied the ruins of my former workplace.

The east wing, where the lift had been, was completely gone. Nothing remained except concrete dust and twisted reinforcing bars.

A demolition worker passed near the fence carrying a clipboard.

"Excuse me," I called.

He looked over.

"What's happening to the underground levels?"

He frowned. "What underground levels?"

"Beneath the main building. There are three levels below ground."

He shook his head. "Not on our plans. We've only got the main structure and foundations." He studied me more closely. "You used to work here, did you?"

I nodded. "For four years."

"Government work, was it?" he asked, lowering his voice. "Defence, Cabinet Office, or energy?"

"Something like that."

"We got the contract last week. Rush job. They're paying three times the usual rate to have the place gone by the end of the month."

The announced closure date had been 31 July. They had started tearing the establishment down early. Whatever Code Wayward meant, our breach had plainly accelerated a shutdown plan that was already prepared.

"What happened to everything inside?" I asked.

"Computers, equipment, files? All cleared out before we arrived. Place was empty. Looked as if everyone had walked away and somebody had locked the doors behind them."

He checked his watch. "I'd better get back. Supervisors are strict about breaks."

As he walked away, I stared at the demolition site. Were they destroying all evidence of the building while sealing the underground chambers beneath it? Had L3 been emptied? Had the preserved soldiers, the children and the machinery that sustained them already been moved to another DAR site?

I remained there for nearly an hour, watching the systematic destruction of a building that had never revealed its true purpose to most of the people working inside it. At last, a security guard noticed me and began walking towards the fence. I returned to my car and drove away before he could question me.

Back at my flat, I opened my laptop and began searching public UK government records.

During my four years with the DAR, I had worked with departmental accounts and reporting systems. My credentials had been revoked, but I still knew the public-facing portals and the language used to conceal expenditure. I searched Ministry of Defence publications, contract notices, archived GOV.UK pages, Companies House records and spending reports issued by the Department for Energy Security and Net Zero.

I found nothing.

Every public reference to the Directorate for Anomalous Research had disappeared. Reports that had once contained oblique entries connected to the DAR now showed the money assigned elsewhere. Some of the expenditure appeared to have passed through energy accounts before being routed into Ministry of Defence budgets. Research announcements I distinctly remembered had been altered to credit other departments or outside contractors.

It was as though somebody had methodically erased every digital trace of the organisation. The few references I recovered from archived pages led to dead links or redirected to unrelated government websites.

The next morning, Thursday, 30 July 2026, I went to the Wiltshire Police enquiry office in Salisbury. The officer behind the desk listened with a weary expression as I explained that I wanted to report a missing person.

"Name of the missing individual?"

"Thomas Keane."

"Your relationship to Mr Keane?"

"Former colleague and friend."

"When did you last see him?"

I hesitated. "On Sunday, 12 July. At work."

"And where was this?"

"A restricted Ministry of Defence research establishment on Salisbury Plain. It was operated by the Directorate for Anomalous Research. The DAR."

The officer stopped typing and looked up. "The Directorate for what?"

"Anomalous Research. It was a covert research body operating through the Ministry of Defence."

He searched his computer, then frowned. "I can't find any record of such an organisation. Which department did it come under?"

"Defence, officially. There may have been Cabinet Office involvement, and some funding was concealed through energy spending. I handled specialised accounts, but they never told us the full structure."

"I'll need the address of this establishment and contact details for your supervisors."

I gave him the coordinates and the names Officer Alistair Vane and Officer Ruth Calder had used. He made a telephone call, speaking quietly and glancing at me several times. When he put the receiver down, his manner had changed.

"Mr Mercer, we cannot establish that this workplace existed. The location you have provided is recorded as a decommissioned meteorological station which had been unused for years. There is no record we can locate of a Thomas Keane employed by the Ministry of Defence or by any agency operating at that site."

"That's impossible. I worked there for four years. Tom worked there too. There were nearly forty employees."

"Do you have employment records? Payslips? A staff pass?"

My pass had been confiscated when the DAR escorted me out. The dismissal letter had been deliberately worded to avoid naming the organisation, referring only to my previous employer. My electronic payslips had vanished with my access to the staff portal.

"If your friend is genuinely missing," the officer said, his tone softening, "we need verifiable information. A home address, telephone number, family contacts, a recent photograph. Can you provide any of those?"

I could not.

Thomas had been intensely private. I believed he had a sister called Helen Keane in Newcastle upon Tyne, but I had no address or telephone number for her. His personnel file had disappeared overnight. Photographs from staff events had been stored on my issued mobile, which the DAR had taken from me.

"I'm sorry," the officer said. "Without enough information to identify him, there is very little we can do."

I left the enquiry office understanding with perfect clarity what had happened. Thomas had not merely vanished from those tunnels. He had been erased from official existence. His records, his employment history and every trace that could prove he had worked at the establishment had been systematically removed.

The DAR had been remarkably thorough. It had demolished the building, erased its public history and removed the records of the people caught in Code Wayward. The speed with which our dismissal folders had appeared now made sense. The protocol had not predicted that Michael, Thomas and I would enter L3, but it had been rehearsed for anyone who did.

The following week, I gave notice on my flat and packed my belongings into a small hired box van. Salisbury held too many memories and too many ghosts: Michael's empty flat across town, Thomas's absence and the knowledge that, a few miles away on the Plain, workers were destroying the final visible evidence of what we had found.

I chose Sheffield almost at random. It was far enough away to feel like a fresh start, yet close to open country where I could walk when the walls of a room became unbearable.

I rented a small one-bedroom flat and sent out applications, relying on my accountancy experience while carefully omitting the DAR from my CV. Within two weeks, a small Sheffield accountancy practice hired me to handle the books of local traders and limited companies. The work was straightforward and undemanding, exactly what I needed.

I spent my days among numbers that behaved properly: figures that balanced and problems with definite solutions. Nothing resembled the inexplicable horror beneath Salisbury Plain.

The nights were harder.

Sleep came reluctantly and brought vivid dreams. Corridors stretched endlessly into darkness. Walls whispered urgent warnings. The preserved bodies stood in perfect rows, their clouded eyes somehow following me through the chamber.

Sometimes Thomas stood among them, his face waxy and motionless but his eyes alive with recognition. Sometimes Michael hung suspended like the others, his lips moving as he tried to tell me something I could not understand.

I would wake gasping, certain that whispers were passing through the radiator, extractor vents or water pipes. The sound always faded as I became fully conscious, leaving me unsure whether it had been real or imagined.

After weeks of broken sleep and exhausted days, I bought a notebook and began to write. At first, I recorded only disconnected memories: the cold air that had rushed from the lift when its doors opened at L3, the precise blue of the keypad light and the rhythm of the voices behind the walls.

Gradually, I organised those fragments into a coherent account. I began with the lunch break on Sunday, 12 July 2026, when Michael first proposed exploring the restricted levels. Each evening after work, I filled page after page with detailed descriptions of everything we had seen and endured.

I recorded the timeline, the underground corridors as I remembered them and the first three-way junction where Michael had gone right, Thomas straight ahead and I left. I described the preserved soldiers in their ordered ranks, Michael's discovery of the children, the warnings whispered through the walls, the unidentified shadow beside the lift and Michael's insistence that it had not been Thomas.

I wrote about Thomas's disappearance and Michael's worsening obsession. I documented the practised efficiency with which the DAR had removed us, the nine months' salary paid to secure our dismissal, the threats of prosecution under the Official Secrets Acts and a potentially lengthy prison sentence, and the subsequent erasure of every trace.

Writing was painful but necessary. Each session left me drained, yet somehow lighter, as though moving the memories on to paper reduced their weight inside me.

I was not writing for publication, nor even for another person to read. It was partly therapy and partly a record of events I feared might one day resemble delusion, even to me. As the months passed, the nightmares became less frequent. The whispers faded from the pipes and vents, although I still sometimes heard them in the interval between sleep and waking.

My life in Sheffield settled into a routine. Work. Occasional walks in the Peak District. Quiet evenings with books or streaming programmes. I made few friends and sometimes went on dates, but I kept everyone at a careful distance.

How could I explain what had happened? How could I tell anyone what it had made of me?

The secret formed an invisible barrier between me and everybody else. One notebook became three, then five, then twelve. I bought a fire-resistant document safe in which to keep them, uncertain whether I was protecting them from accidental destruction or preventing other people from reading them.

Perhaps it was both.

In my final notebook, I addressed an imagined future reader. Perhaps somebody would find my account after my death. Perhaps another survivor of something similar would discover it while searching for proof that they were not losing their mind.

For that unknown reader, I set down the conclusions I had reached.

Some government bodies operate beyond public knowledge and meaningful oversight. Some research programmes continue for decades without scrutiny. Some discoveries are concealed not because they would endanger national security, but because they defy explanation and every acceptable ethical boundary.

I wrote about the cost of curiosity. Michael was dead. Thomas was missing, presumed trapped and possibly dead. Two friends had been lost because we could not resist entering a place where we did not belong.

I described how quickly an organisation could erase its operational footprint and the official existence of those connected to it.

Most importantly, I wrote a warning.

If you find an abandoned research establishment, a sealed door protected by unusual security or a lift that descends farther than the plans admit, walk away.

Report nothing. Tell no one. Return to your ordinary life and try to forget what you saw.

Somewhere beneath the demolished remains of a non-descript concrete building on Salisbury Plain, those chambers may still exist. The preserved bodies may still stand in perfect rows. The voices may still whisper warnings into empty corridors.

Or perhaps L3 was emptied before the demolition. Perhaps the soldiers and children were transferred to another DAR site, hidden beneath another patch of restricted land. Project Afterimage might have been nothing more than a name Michael found during his collapse, attached to declassified Cold War behavioural-research papers from the 1970s, alleged consciousness studies from the 1980s and rumours exchanged on a dark-web forum. It might also have been real.

And somewhere, in the sealed levels beneath Salisbury Plain or in some relocated facility, Thomas might stand among new specimens. His eyes might be clouded but aware, his consciousness trapped inside a body incapable of movement, his voice joining the others in the walls as he tries to warn anyone who approaches.

Or tries to call them closer.

I closed the final notebook and locked it in the safe with the rest.

Beyond the window of my Sheffield flat, the city continued its normal evening rhythm. People walked dogs. Couples headed out for dinner. Students returned from evening lectures. None of them knew what might exist beneath the surface of their world. None of them had heard the voices.

I had come to understand that their ignorance was a blessing.

Once you hear voices inside the walls, once you see what waits in those underground chambers, you never truly escape. You can only live with the knowledge, carry on despite it and warn others away from the same discovery.

Even now, I sometimes wake to a whisper travelling through the pipes. It may be the building settling. It may be trauma giving shape to ordinary sounds. It may be Thomas, still conscious somewhere below ground.

I no longer try to decide.

Some curiosities are too dangerous to satisfy. Some doors should remain locked. Some secrets should stay buried deep underground, hidden from those who cannot understand the price of uncovering them.
